Plane falls 4000m after losing power in both engines

Singapore Airlines jet on way to Shanghai plunges 4,000m
An investigation is underway after a Singapore Airlines Airbus A330-300 with 194 people on board lost power in both engines while flying from Singapore to Shanghai. The incident happened on May 23 when the flight encountered a “huge storm”, the airline said.
Flight SQ836 plummeted 13,000ft around three-and-a-half hours after departure as “both engines experienced a temporary loss of power and the pilots followed operational procedures to restore normal operation of the engines.”
It added: “The flight continued to Shanghai and touched down uneventfully” at 22.56 local time. The two Rolls-Royce engines “were thoroughly inspected and tested” on arrival in Shanghai, with “no anomalies detected.” The storm occurred over part of the South China Sea off China’s southern coast.The Guardian
